Product details
Overview
M24C08-DRDW3TP/K from STMicroelectronics is an AEC-Q100 Grade 1 automotive EEPROM with I²C interface supporting up to 1 MHz clock, 8 Kbits (1024 × 8) memory organized in 64 pages of 16 bytes each, and integrated ECC logic for single-bit error correction. It operates from 1.7 V to 5.5 V across –40 °C to +125 °C and includes a dedicated 16-byte identification page for device ID and application parameters.
For engineers reviewing the M24C08-DRDW3TP/K datasheet, M24C08-DRDW3TP/K pinout, M24C08-DRDW3TP/K application, or M24C08-DRDW3TP/K equivalent, key selection criteria include automotive-grade reliability at 125 °C, write protection via WC pin, page-write capability within 4 ms, and compatibility with Fast-mode Plus (1 MHz) I²C timing.
Technical Context
The M24C08-DRDW3TP/K implements a fully compliant I²C target protocol with START/STOP detection, ACK/NACK handshaking, and 7-bit device addressing extended by E2 input for dual-device bus configuration. Its internal address counter auto-increments during sequential reads and supports random, current-address, and sequential read modes.
It integrates on-die ECC x1 logic that transparently detects and corrects single-bit errors per byte during read operations, and features Schmitt-trigger inputs on SCL/SDA for robust noise immunity. The WC pin enables hardware-level write protection independent of software commands, and the identification page supports permanent lock into read-only mode after programming.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C08C-SSHM-T | 8-Kbit I²C EEPROM, AEC-Q100 Grade 2 (–40 °C to +105 °C), no embedded ECC, 5.5 V max supply | Limited to under-dash modules; lacks ECC and 125 °C rating for powertrain use | Select only for cost-sensitive cabin applications where ECC and full Grade 1 temp range are not required |
| BR24G08NUX-100 | 8-Kbit I²C EEPROM, AEC-Q100 Grade 1, 1.7–5.5 V, but only 400 kHz max clock and no identification page | Suitable for legacy CAN gateway modules needing lower-speed I²C; missing ID page limits secure boot use cases | Prefer when system clock budget restricts to Fast-mode only and device authentication is handled externally |
Compared with AT24C08C-SSHM-T and BR24G08NUX-100, the M24C08-DRDW3TP/K uniquely combines 1 MHz I²C, on-die ECC, and a lockable identification page - making it the only choice for ASIL-B/C automotive subsystems requiring both high-speed parameter logging and cryptographic binding.

FAQ
What is the function of the E2 pin on the M24C08-DRDW3TP/K?
The E2 pin configures bit b3 of the I²C device select code (1010/E2/A9/A8/RW), enabling two M24C08 devices to share the same I²C bus with distinct addresses. It must be hardwired to VCC or VSS; floating defaults to low. This allows flexible bus topology without external address jumpers or resistors.
How does the identification page differ from main memory in usage?
The 16-byte identification page contains factory-programmed ST device ID (bytes 0–2) and user-programmable space (bytes 3–15). Unlike main memory, it supports dedicated instructions for read/write/lock, and once locked, becomes permanently read-only - ideal for storing immutable calibration or security keys.
Can the M24C08-DRDW3TP/K operate reliably at 1.7 V with 1 MHz I²C clock?
Yes - the device is fully specified for 1 MHz Fast-mode Plus operation down to 1.7 V supply, with guaranteed timing margins per DS10156 Rev 8 AC characteristics. At 1.7 V, setup/hold times are relaxed but remain compliant when using standard I²C master drivers with appropriate pull-up strength.
What happens if a page write crosses a 16-byte boundary?
A page write crossing the 16-byte boundary triggers roll-over: data beyond the current page wraps to the start of the same page, overwriting earlier bytes. For example, writing 18 bytes starting at address 0x0F fills 0x0F–0x1F, then overwrites 0x00–0x01. Software must enforce page alignment or split writes manually.
